Short-wave Infrared Camera Enables Real-time Monitoring of Photoelectric Masts of Maritime Cargo Ships

Application of short-wave infrared camera in real-time monitoring of photoelectric masts of maritime cargo ships

The short-wave infrared camera adopts the latest detector technology, 640x512 high resolution, 15um pixel spacing, and has extremely high sensitivity in the 0.9um~1.7um band. The camera features low dark current and high dynamic range, and precise TEC temperature control further reduces read noise.

SWIR cameras have a major advantage unmatched by other technologies, that is, SWIR cameras can image through glass. For SWIR cameras, special expensive lenses or housings adapted to harsh environments are almost unnecessary.

A unique feature of short-wave infrared cameras is that the images of faces are still clear in various environments. Another advantage of SWIR imaging is the ability to see through tinted glasses.

Short-wave infrared cameras are less affected by atmospheric scattering, have strong ability to penetrate fog and smoke, and have a long effective detection distance. The adaptability to climatic conditions and battlefield environments is significantly better than that of visible light imaging.

Under the night vision condition of atmospheric glow, the photon irradiance is mainly distributed in the SWIR band range of 1.0-1.8 μm, which makes SWIR night vision imaging have significant inherent advantages compared with visible light night vision imaging.

The multi-spectral application of short-wave infrared cameras is different from the traditional single broadband imaging technology. The multi-spectral and hyper-spectral imaging of short-wave infrared cameras combines imaging technology and spectral measurement technology. The information obtained includes not only two-dimensional spatial information, but also wavelength-dependent information. The spectral information of the distribution, forming a "data cube".

The optoelectronic masts of modern submarines require multispectral imaging and detection, which is very important and has not yet been used in imaging in the near-infrared spectrum.

SWIR imaging is a useful complement to thermal imaging cameras for enhanced vision and poor weather conditions with low visibility. Thermal cameras are good at detecting a warm target against a cold background, whereas SWIR is good at identifying what the target is, eg (ships, vehicles, people).

Due to the thermal intersection, the details of the coast and seawater are lost in thermal imaging. Shoreline images stand out because SWIR can image reflected light rather than relying on temperature differences, and SWIR cameras can capture more detail than visible-light cameras due to SWIR's ability to penetrate fog.
